Název v původním jazyce

Spectral and intensity sensitivity of insect light-dependent magnetoreception.

Popis výsledku v původním jazyce

It has been shown on various animal taxa that magnetic compass behavior depends on presence and wavelength of light. Crucial role of short wavelength half of spectrum in magnetoreception is consistent with process of constitution of radical pairs consisting of cofactor flavin (FAD) and protein Cryptochrome (Cry). The investigation of light wavelength and intensity thresholds for magnetic sensing in vivo gives important data underpinning experimental identification of radical partners. To date, only fruitfly and birds wavelength limits were reported (&lt;420 nm and &lt;565 nm respectively) yet generally without mapping of color-specific intensity thresholds throughout the spectrum. Here, we tested spontaneous reaction to rotations of geomagnetic horizontal vector - magnetically induced restlessness of German cockroach (Blattella germanica ) under 365, 385, 405, 466 and 520 nm lights and defined respective light intensity thresholds.
